If the iron be blunt, and he do not whet the edge, then must he put to more strength: but wisdom is profitable to direct.

Eccl.10.10

Remember: The duller the ax the harder the work; Use your head: The more brains, the less muscle.

Eccl.10.10

If the ax is dull and its edge unsharpened, more strength is needed but skill will bring success.

Eccl.10.10

If the ax is dull, And one does not sharpen the edge, Then he must use more strength; But wisdom brings success.
